MANUFACTURE OF SHOVELS.

SPECIFICATION forming part of Letters Patent No. 491,944, dated February14, 1893.

' Application filed July 21, 1892. Serial No. 440.808. (No model-) i Toall whom it may concern:

Be it known that PATRICK W. GROOM, deceased, of St. Louis, Missouri,made a new and useful Improvement in the Manufacture of 5 Shovels, ofwhich the following is a full, clear,

and exact description.

The invention is an improved mode of making shovels and analogous toolshaving handlestraps integral with the body of the tool.

[ I prepare, by any suitable means, a straight, flat, iron or steel bargrooved or channeled longitudinally in its side edge, or in its sideedges according as the bar is designed for making single or doubleshovel-blanks, and

i then cut the bar transversely into blanks of a suitable length formaking a shovel-blank. The blank is then rolled in a directiontransversely to its longitudinal axis; that is,transversely to thelongitudinal axis of the ulti- 2o mate shovel, until the solid portionof the blank has been widened sufficiently or thereabout, to form thewidth of the shovel. The grooved portions of the blank, however, do notmaterially widen during the rolling just described, the upper and lowerparts .of the blank containing the grooves in practice merely comingtogether or substantially together. The blank thus reduced is thenrolled in the direction of the length of the shovel, or shovels as thecase may be, ultimately made from the blank, by which operation the wideportion of the blank is elongated sufficiently for the blade of ashovel, or of two shovels, according as the blank is a single or 3 5 adouble one, to be made therefrom by the customary means employed incutting shovels out of shovel blanks, and the remaining portions of theblank (described above as the grooved portions) are elongatedsufficiently 0 for the straps of the shovels to be made therefrom by thecustomary means employed in forming shovel-straps out of shovel blanks.The usual socket, which it is desirable to have in the blade at thepoint where the straps join 5 the blade is, when used, preferably formedby puncturing the blank before it is rolled.

The annexed drawings, making partof this specification, illustratesubstantially the various steps of the process under consideration.

Figure 1 therein is a View in perspective of the bar from which theblanks are out; the broken lines indicate the blank-lengths: Fig.

2 is a plan of a blank cut from the bar; the broken lines indicate thelines of the channets in its side edges and the position of thepunctures made in the blank to form the sockets in the shovel-blades:Fig. 3 is a vertical, longitudinal section on the line 3-3 of Fig. 2:Figs. 4 and 5, are, respeotively,a plan and a side elevation of theblank after it has been rolled transversely; Fig. 6 is a view inperspective of the finished double shovelblank: and Fig. 7 is a view inperspective of one of the shovels out from the double shovel blank andready to be finished.

The same letters of reference denote the same parts.

A represents the bar from which the blanks may be obtained. It is ofsuitable proportions for the purpose in question, and it has a channel ain each of its side edges 60, a, for forming a double blank B, Figs. 2,3, that is, a blank from which a double shovel blank is made. For whilethe hereindescribed process can be employed in making a shovel 7 blankhaving straps at but one end only, it is profitable to apply it inmaking the double shovel blank described, as the double blank can beheated, and in reducing it, can be passed through the rolls,substantially as read- I ily as can be a single blank. The sockets, 03,Figs. 2, 3, and at, can be formed in the blank B by any means suitablefor puncturing iron in the form shown.

The reduction of the blank B into the form shown at 0, Figs. 4, 5, iseffected, preferably, by passing the blank through suitable rolls suchas used in rolling mills for reducing metal bars or plates of a natureanalogous to the one under consideration. The blank is 0 rolled in bothdirections as indicated by the double headed arrow 00, Fig. 2, asthereby the metal in the central portion 1) of the blank is transferredevenly to both sides of the blank as shown at c 0 Figs. 4, 5. In thisoperatiou 5 the blank is proportionately reduced in thickness, and theparts b, I), closed together, substantially as shown in Fig. 5. Theblank,

thus reduced, is then rolled, forward and backward as indicated by thedouble headed arrow y, Fig. 5, in the direction of the length of theblank, and it is thereby reduced still more and shaped into the formshown substantially atD Fig. 6, in which d represents the body of theblank, and d, d, at each end of the body, a divided tang. Then,bydividing the double shovel blank D transversely, as indicated by thebroken line 2, Fig. 6, two single shovel blanks (Z (Z can be formed, andout of each of these single shovel blanks a shovel E, Fig. 7, can bestamped in the usual manner, the body or blade of the shovel coming outof the part (Z of the body of the blank and the shovel straps coming outof the divided tang d. The usual means, such as the introduction of sandor dust therein, may be used to prevent the divided tang-portions, inrolling the blank, from being welded together. In carrying out the firsttwo steps of the method hereindescribed and claimed; that is, inproducing the blanks B, Figs. 2, 3, the right is claimed, and wished tobe so construed, to employ any equivalent step or steps. That is, saidblanks B might be forged, cast,or otherwise formed directly andseparately, instead of being cut from a bar such as the bar A.

The bar, A,is shown flat uponits upperand under surfaces. This isdesirable, although not absolutely essential, as a fair result can beobtained from a bar not strictly fiat.

What is claimed as the invention is- The hereindescribed improved methodof producing blanks for shovels and analogous tools having handle-strapsintegral with the body of the tool, the same consistingin making a bargrooved or channeled in its side edge or side edges, then cutting saidbar transversely into blanks, then reducing said blanks and widening thesolid portion of the blank as described, and then further reducing theblank and elongating both its solid and its grooved portions to form thedesired shovelblank.
